Product Background – Shuttering Magnet

When we set out to shuttering magnet manufacture, we were not about to go small. We have a team of in-house magnetists here at Magprecast who create these advanced magnet arrangements. The precast concrete magnet has an incredible magnetic field strength and suction force. The suction force is over 200 times its own weight. Through the interaction of the magnetically conductive materials, the arrangement of the magnetic lines of the individual magnets change.

Usage

When the Precast concret magnet is in use, the bottom of the magnet is firmly attached to the steel mold platform. (The magnet and the platform form a complete magnetic circuit closing system.) This circuit exhibits an ultra-strong holding force. The shuttering magnet will not budge, slip, or shift while in use, making it much safer and user-friendly.

Lifting the magnet to the platform

When the precast concret magnet is not in use, there’s a gap between the magnet and the platform. The magnetic circuit is not saturated, and the holding force is reduced. This is the time to pry the shuttering magnets open with a tool and begin using it with the platform.

Instructions for safe use

To ensure your shuttering magnets magnets can last through countless uses, be sure to treat them with care. Below are some tips on how you can help lengthen the lifespan of your shuttering magnet.

Precautions

Much like anything else, there are some precautions to take when using our magnets. These are not only for your safety but to ensure the precast concrete magnet performs as it should.

Clean shuttering magnets
Clean shuttering magnets

1. The internal components of the neodymium magnet must be kept clean. Avoid debris entering the template magnet. If foreign material makes its way in, the magnetic force will be in jeopardy.

Operating temperature warning

2. The maximum operating or storage temperature must be below 80 ° C. Higher temperatures may cause the template magnet to decrease or lose its magnetic force completely. The temperature of a standard curing furnace is below 60 ℃ so the magnet can enter directly. If the curing furnace’s temperature is higher than 80 ℃, remove the magnet before entering the curing furnace.

No access for Persons with Pacemakers

3. Keep the shuttering magnet away from electronic devices and unnecessary ferromagnetic metals. This includes mobile phones, tablets, smartwatches, laptops, and computers. Almost no magnetic force is felt outside the steel casing of the shuttering magnets, but the magnetic force inside is extremely strong.

Safety note* If someone wears a pacemaker, extra care should be taken because strong magnetic fields can damage electronic devices inside the pacemaker.

avoid pinching your hands

  1. To avoid pinching your hands, always handle with care. Stack the magnets gently, and always look out for your fingers and hands.

FAQ

Why does the fixed effect of shuttering magnets weaken over time?

This happens when there are foreign objects (such as concrete, iron filings, film, etc.) on the bottom of the product or misalignment of the magnet, it can’t properly attach to the platform. You won’t get the same holding force, and it can weaken the magnet over time.

How can I prevent damage to my magnet?

Try to be as gentle as possible. Yes, the magnets are tough and can withstand regular usage, but if they’re banged around or mistreated, they won’t perform at their absolute best.

The physical properties of the damaged NdFeB material inside the magnet are hard and brittle.

Therefore, the magnet should not be impacted or thrown around by external force. Nor can the two magnets be attracted to each other. If the magnet inside the product breaks and damages the body, the product cannot be used.

When will I receive my shuttering magnet?

Most orders will be shipped out within 3-5 days. We try to keep our inventory high to reduce waiting times. If you need a customized precast concrete magnet or a logo, contact us to learn more.

Will the magnet lose tension over time?

Every magnet will lose some tension over time. Magprecast uses high-quality magnets to ensure our loss rate is only 1% within the first 10 years of use.
